脉冲追赶式同步扫描过程中,双基地雷达的目标分辨力不仅与雷达参数有关,而且还与脉冲追赶进程密切相关.分析了双基地雷达距离、角度和多普勒分辨力的影响因素,并对其在脉冲追赶情况下的变化规律进行分析,结果表明在每一脉冲追赶扫描周期内,双基地雷达的距离分辨力和多普勒分辨力不断提高,而角度分辨力则有所下降. 相似文献

We model an infinitely repeated Tullock contest, over the sharing of some given resource, between two ethnic groups. The resource is allocated by a composite state institution according to relative ethnic control; hence the ethnic groups contest the extent of institutional ethnic bias. The contest yields the per-period relative influence over institutions, which partly spills over into the next period, by affecting relative conflict efficiency. Our model generates non-monotone evolution of both conflict and distribution. Results suggest that external interventions, when effective in reducing current conflict and protecting weaker groups, may end up sowing the seeds of greater future conflict. 相似文献

The resource debate is easily discerned as part of the ongoing history of farmer–herdsman conflict in the North Central region of Nigeria. Scarcity theorists are adept at linking scarcity with the onset of livelihood conflict while on the other hand resource abundance pundits insist it is profusion and not scarcity that impels conflict. This article traverses these wrangles and proceeds to downplay the resource polemic altogether. It is proposed that the resource debate, despite its profoundness, presents a narrow reading of farmer–herdsman clashes in Nigeria’s North Central region. It is suggested that a number of other factors, including elite land grabbing, ethno-religious identity construction, weak state capabilities, the citizenship question, corrupt traditional institutions, the lack of an effective land tenure system and a widespread culture of impunity, make for better readings of the conflict. Owing to the negative impacts of the conflict on state and society, it is recommended that the state in Nigeria should commit itself to addressing the citizenship question, strengthening the capabilities of security institutions, extirpating the culture of impunity and revaluing its policy on land redistribution. 相似文献

Many researchers have focused on the role colonialism has played in causing interstate border disputes in Africa. Besides the colonial issue, this paper seeks to investigate what other factors fuel interstate border disputes in Africa and determine how effectively the disputes can be resolved. In recent decades, Africa has been tormented by and is still experiencing numerous interstate border disputes which have serious implications for the disputing states. Some of the disputes are resolved, but violations of human rights and instability still occur in these regions. By analysing the content of some relevant documents and with the use of interviews, this paper reveals that most disputing African states rely heavily on foreign intervention (especially by their erstwhile colonial masters) in the resolution of their disputes. It is argued that African leaders need to be more committed and exhibit better leadership in resolving their border disputes, and that they should always seek the expertise of African forums such as the African Union (AU) before calling for foreign intervention. It is suggested that African leaders and the AU understand the problems of Africans better than anyone else, and they are also the ones mostly greatly affected by these disputes. Thus, there needs to be more of a focus on addressing the root causes of disputes in order to avoid them resurfacing, rather than seeking to merely halt them. 相似文献

Natural resources have been blamed for inducing slow growth and sparking civil conflicts and violence. This paper first develops a model to account for the hazard of armed civil conflicts as a manifestation of the natural resource curse, which is mediated by the quality of both economic and political institutions. We then use recently published data on institutional quality and natural resource rents to measure the potential impact of the resource curse on violent civil conflicts using a panel of data for over 100 countries in the period 1970–2010. Our model explicitly accounts for the role of good economic and political institutions in deterring the recourse to violence as well as the extent to which they might weaken the resource rents effect. 相似文献

The dependence on oil, gas, and mineral exports arguably has a negative impact on economic growth in resource-rich, developing countries. This article looks at the impact of resource dependence on adjusted net savings (ANS) as an indicator of weak sustainability. Our results, based on a panel of 104 developing countries during the recent commodity price boom, confirm a negative relationship between resource extraction and sustainable development as measured by ANS. We further look at the specific role of armed conflict and armed violence as captured by the homicide rate. Armed conflict, which is positively associated with resource dependence, negatively affects ANS per capita according to both our OLS and instrumental variables (IV) estimates. Similarly, armed violence has a detrimental effect on sustainable development. Our IV estimate suggests that a one-point increase in the homicide rate decreases ANS per capita by $60. Since education expenditures are a critical ANS component, we further examine the impact of resource dependence and violence on human capital. Consistent with previous findings, resource-dependent countries underinvest in education but armed conflict and violence do not affect the instantaneous share of education expenditures, hinting at a detrimental effect working through physical and social capital rather than education. 相似文献

北斗导航定位系统播发三个频率观测值,有助于载波相位整周模糊度的快速、准确固定。传统的几何无关模型三频载波相位模糊度固定算法通常采用遍历整数搜索的方法确定载波相位-伪距组合系数,组合后的噪声因子较大,模糊度固定成功率不高。在分析了北斗系统伪距测量误差特性的基础上,给出了加权组合噪声因子的定义及其约束下的最优组合系数的求解方法。采用Hatch滤波提高电离层延时误差实时估计精度,成功固定三组线性无关组合系数对应整周模糊度,进而确定基础整周模糊度。利用北斗系统短基线、长基线实测数据对算法性能进行了验证,实验表明:提出的算法可优化超宽巷、宽巷组合噪声因子20%以上,模糊度固定成功率提高10%~18%左右,30s历元平滑后的基础模糊度固定成功率可达90%以上。 相似文献
